Hello; new to the forum.

My question stems from the lack of information available to me concerning the hydraulic fluid used in the Lull front shovel loader on my 1950 Case model DI.

My Case manuals indicate that SAE 30 is recomended for hydraulics but what appears to be AW 32 or 46 is in the tractor from the previous owner , God rest his soul. The operation of the front loader is fine but there is some weeping from the lift cylinders packing glands .

Climate temperatures at this location vary from -20 to 90 degrees, operating temperatures would be more in the range of 20 to 80 degrees.

So two questions: Is the AW hydralic fluid acceptable for vintage hydraulics? And what is a source for the cylinder packing gland seals?
